Overview

BRIDGE LIVE is a broadcast quality, low latency turnkey system for REMI, Synchronous Multi-Channel Video Contribution, Remote Collaboration, Direct to Audience Streaming, and Multi Bit Rate/Format Delivery.

Equipped with 12G-SDI I/O plus the power and flexibility to enable real time bidirectional encoding, decoding, and transcoding for critical UltraHD and HD workflows, BRIDGE LIVE is an essential part of any modern live video production toolkit. A compact and robust 1RU form factor with redundant power supplies and a 3 year warranty means peace of mind even when dealing with the most demanding applications.

Whether facilitating remote production, two-way interviews, live event streaming, synchronous multi-cam backhaul with HDR, cloud contribution, program return, confidence monitoring, collaborative production, ABR ladder profiles to hand-off for OTT packaging, BRIDGE LIVE ensures simultaneous, secure, and stable workflows whether over private lines or the public internet.

AJA and Comprimato

BRIDGE LIVE represents an exciting partnership between AJA and Comprimato, both long standing industry innovators. The merging of AJA’s hardware development and video I/O expertise with Comprimato’s transcoding and internet transport know-how means customers can expect the versatility, speed, and quality needed for that competitive edge. The unique fusion of company talent between AJA and Comprimato ensures that BRIDGE LIVE delivers the performance, reliability, and ease of use needed for critical live encode, decode, or transcode needs.

NDI Encode/Decode/Transcode

Starting with v1.12 software, BRIDGE LIVE includes support for NDI (Network Device Interface), the high quality, real time, low latency live video standard developed by NewTek. BRIDGE LIVE can support up to 4 simultaneous 60p HD encodes/decodes or 1x 30p UltraHD encode/decode to/from SDI. BRIDGE LIVE’s NDI functionality offers:

  • SDI to NDI (encode)

  • NDI to SDI (decode)

  • IP Video Streams to NDI (transcode)

  • NDI to IP Video Streams (transcode)

Used in conjunction with BRIDGE LIVE’s broad codec and protocol support, collaboration between geographically separated (remote) NDI facilities can be realized.

BRIDGE LIVE provides broad NDI product compatibility across software and hardware transmitters and receivers.

Synchronous Multi-Channel Transport

5637-AJA_BRIDGE_LIVE_Multi_Sync_trans_backhaul.jpg

BRIDGE LIVE can take independent SDI source inputs, and maintain their synchronous relationship while transporting the content to end-point destinations.

This functionality can take place between a pair of BRIDGE LIVE units for a synchronous end-to-end SDI workflow, often referred to as SDI backhaul, or site-to-site SDI workflows.

BRIDGE LIVE’s synchronous multi-channel capability is also supported for cloud contribution, whereby a BRIDGE LIVE system can send to a cloud instance of Comprimato Live transcoder software, for delivery to various platforms / cloud services as IP video.

Furthermore, Synchronous Multi-Channel Transport can be scaled up from a single BRIDGE LIVE pair to additional BRIDGE LIVE pairs, to enable workflows where multiple BRIDGE LIVE systems can be receiving SDI and sending to multiple BRIDGE LIVE systems outputting SDI, all in synchronicity.

For end-to-end SDI workflows, HDR is also supported.

Workflow Flexibility and Interoperability

Use BRIDGE LIVE in conjunction with multiple third party systems and software to achieve your workflow requirements as they evolve. And of course, AJA’s own HELO Plus can be used for contribution or aggregation with BRIDGE LIVE.
